I do not see where all these go on the valve covers.

 

This might help:



The smallest 28 'O' rings go on the cam cover bolts (6), the largest 8 are the spark plug boss seals (3), and the 4 mid-size are the centre seals (4). Consider replacing the VVT valve seals (9) as they seem to be troublesome on the AJ27.

 

They are called ISOLATORS!!!!!!!!!!!!!!!

 

Thanks, Bob - I should have described them more accurately.

The cover gaskets themselves look really skinny compared to those for the earlier AJ26.
